EGR stands for “Exhaust Gas Recirculation”. Put simply, it recycles your exhaust gases back into your engine in order to reduce the amount of gases and pollution put into the atmosphere by your car it’s an emission control things
Some people say you should blank off of your EGR valve with a plate. Other advise against it.
If you clean the EGR valve every 20, 000 km you will be helping the environment and won’t be breaking the law and your vehicle will have a better chance of running a lot better than it most probly is or be like the day you picked the your vehicle up from the car yard
A lot of the new Diesel engine vehicles and are now beginning to use Add blu which you might have started to see at your local service stations. Ad Blue converts harmful NOx from your diesel vehicle exhaust into harmless nitrogen and steam, therefore considerably reducing the emissions of nitrogen oxides
Some diesel engines need AdBlue to help them meet tough Euro 6 emission control that regulate the level of harmful emissions can come out of a car’s exhaust.
AdBlue isn’t mixed with the diesel fuel. Instead, it works with the exhaust gasses after they come out of the engine. It is injected into the exhaust gases and burnt at very high temperatures to break down harmful nitrogen oxides
If you accidentally pour AdBlue into the fuel tank, don’t start the car. The fuel tank will need to be drained.
I digress back to the EGR
The EGR system is a necessary evil (to your engine petrol or Diesel) to reduce pollution emissions. As such, whilst it is good for the environment, it can be bad for your engine.
the main purpose of keeping the EGR clean and working is to deal with
- Performance gains (including better fuel consumption, smoother boost/power delivery).
- Quieter running engine.
- Clean, fresh air intake.
- No limp mode or fault codes.
